7.12 : 内部収益率

The Internal Rate of Return is a financial analysis tool used to evaluate the profitability of potential investments. It uses the same concept as net present value.

The internal rate of return is the break-even interest rate at which the sum of the present values of all cash inflows is equal to the initial investment.

This rate helps businesses and investors decide whether to proceed with a project or investment.

The internal rate of return is compared to the required rate of return, which is the minimum profit percentage investors expect from an investment considering its risk and opportunity cost.

Consider an example of a Pharmahealth company evaluating an investment in developing a new drug.

Pharmahealth uses the internal rate of return to determine if the new drug project is a worthwhile investment.

The internal rate of return is the rate that will make the net present value of all expected cash flows from the project equal to zero.

Internal rate of return calculates a single percentage figure representing the expected annual rate of return, making it easier to compare different investments regardless of their size or duration.
